Filter capable of conveniently replacing filtering bag

Abstract

The invention provides a filter capable of conveniently replacing a filtering bag. The filter comprises a shell body, wherein a sealing cover is arranged at the upper end of the shell body; a barometer is mounted at the upper end of the sealing cover; the sealing cover is fixedly connected with the shell body through a connection mechanism; a U-shaped rod is welded at the upper end of the sealingcover; the other end of the U-shaped rod is connected with a rotary mechanism; the shell body is internally provided with a filtering mechanism. The filter provided by the invention has the advantagesthat the filter is stable in structure; the sealing cover is simple and convenient to open and external tools are not needed; the sealing cover can be easily moved through rotating a rotary table, sothat the energy and time of workers are reduced; the inner part of the shell body is also convenient to repair and a filtering bag is convenient to replace; a movable block is rotated and two clamping blocks can be pulled out through a sliding groove, so that the filtering bag also can be conveniently and rapidly replaced; the pressure in the shell can be known through the barometer, so that whether a filtering screen in the filtering mechanism is blocked or not is judged, and furthermore, the filtering bag is convenient to replace in time by the workers.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a filter for easy replacement of filter bags. Background technique [0002] The existing water treatment technology is more and more developed. For the treatment of part of the working wastewater and sewage with complex components, a large number of additives and sophisticated filtering equipment are required for effective treatment, so that the wastewater can be filtered clean. However, most of the existing Sewage only needs simple filtration, and bag filter is widely used because of its good filtering effect and large filtering flow. [0003] Most of the existing bag filters are made of stainless steel, so that the whole is stronger and not easy to rust, so the cover of the bag filter is heavy, and when the bag filter is used, it needs Frequent replacement of filter bags is required to ensure the filtering effect of the bag filter, but the weight of the cover is heavy,...

[0002] The existing water treatment technology is more and more developed. For the treatment of part of the working wastewater and sewage with complex components, a large number of additives and sophisticated filtering equipment are required for effective treatment, so that the wastewater can be filtered clean. However, most of the existing Sewage only needs to be filtered simply. Bag filter is widely used because of its good filtering effect and large filtering flow.

[0003] Most of the existing bag filters are made of stainless steel, so that the whole is stronger and not easy to rust, so the cover of the bag filter is heavy, and when the bag filter is used, it needs Frequent replacement of filter bags is required to ensure the filtering effect of the bag filter, but the weight of the cover is heavy, which makes it inconvenient for the staff to replace the bag filter; most of the filter bags of the existing bag filters are installed in the In the support frame, the support frame needs to be removed together when replacing, so as to facilitate the installation of the filter bag, but most of the existing support frames are fixed on the support plate in the filter by bolts, which makes it inconvenient for the staff to install and replace the filter bag
